Abstract

Manual static chamber is one of the most widespread methods for the quantification of greenhouse gases (GHGs) emissions from agricultural systems. But there are concerns about the reliability of measurements and a necessity to assess the static chambers used in the studies performed in the countries of Latin America. Thus, this study aims to investigate the quality of the characteristics from the static chamber methodology, the confidence level of the GHG measurements, and recommend what should be improved. We conducted a systematic review of databases to identify peer-reviewed articles that used the static chamber method in Latin America. A total of 90 articles were analyzed and separated according to the publication year (2000-2008, 2009-2015, 2016-2020). We evaluated eight design and deployment chamber characteristics. The depth of base insertion and type of storage vial received the lowest scores, and the number of samples received the highest score. The description and reporting of the methodological procedures in the studies should be improved. The percentage of articles with high and medium confidence levels increased within the time, and the number of articles with low and very low confidence levels reduced. Scientists/Researchers should continue to follow the protocols, especially the most updated ones.

摘要

手动静态室是量化农业系统温室气体 (GHG) 排放量最广泛的方法之一。但是，人们担心测量的可靠性以及评估在拉丁美洲国家进行的研究中使用的静态室的必要性。因此，本研究旨在调查静态室方法的特性质量、温室气体测量的置信水平，并建议应该改进的内容。我们对数据库进行了系统审查，以确定在拉丁美洲使用静态室方法的同行评审文章。按出版年份（2000-2008、2009-2015、2016-2020）共分析分离出90篇文章。我们评估了八个设计和部署室的特征。碱基插入深度和储存瓶类型得分最低，样本数量得分最高。应改进研究中方法程序的描述和报告。随着时间的推移，置信度高、中的文章百分比增加，置信度低和极低的文章数量减少。科学家/研究人员应继续遵循协议，尤其是最新的协议。并且具有低和极低置信度的文章数量减少。科学家/研究人员应继续遵循协议，尤其是最新的协议。并且具有低和极低置信度的文章数量减少。科学家/研究人员应继续遵循协议，尤其是最新的协议。
